compute_scans(dataset::DimStack, minΔt::Number=-1)

Identify Scan IDs from a given time series and minimum scan seperation. Returns an integer array for the identified scan IDs.

• dataset::DimStack
• minΔt: minimum seperation between the scans in seconds.

compute_scans!(dataset::UVDataSet, minΔt::Number=-1)

Identify Scan IDs from a given time series and minimum scan seperation. Returns an integer array for the identified scan IDs.

• dataset::DimStack
• minΔt: minimum seperation between the scans in seconds.

compute_uvw!(uvdata::UVDataSet)

Recalculate uvw coordinates of the :baseline data set using :usec, :vsec, :wsec, :ν fields. For instance, u is given by usec * ν.

compute_uvw(ds::DimStack)

compute_uvw(uvdata::UVDataSet)

Recalculate uvw coordinates of the :baseline data set using :usec, :vsec, :wsec, :ν fields. For instance, u is given by usec * ν.

compute_ν(uvdata::UVDataSet, datakeys=nothing)

Recalculate the observing frequency ν for data sets given by datakeys.

compute_ν!(uvdata::UVDataSet, datakeys=nothing)

Recalculate the observing frequency ν for data sets given by datakeys.

compute_ν(ds::DimStack)

hdulist2ant(antab)

hdulist2bl(ghdu; ex=ThreadedEx())

hdulist2freq(ghdu, antab, fqtab)

hdulist2hdus(hdulist)

Read the given hdulist (output of pf.io.open) and return GroupHDU and HDUs of AIPS AN/FQ Tables.

hdulist2metadata(ghdu, antab)

identify_scans(t::AbstractArray, minΔt::Number=-1)

Identify Scan IDs from a given time series and minimum scan seperation. Returns an integer array for the identified scan IDs.

• t::AbstractArray: time stamps
• minΔt: minimum seperation between the scans. should be in the same time unit with t. Default to 2 x minimum seperation

load_uvfits(filename::AbstractString)::UVDataSet

load visibility data from the given uvfits file. Data will be loaded through astropy.io.fits module loaded by PyCall.
